Rare failure in electronic anti -theft in Xsara Picas

Hello, I am new in the forum and first of all greet you, I have an Xsara Picasso and sometimes it fails to start and I get the message of "electronic anti -theft" and downside I also get "handbrake" and the messages are exchanged, I also disappear the 0 (zero) of the accounting and I come out two horizontal stripes, after trying many times in many times in the end it starts. I have changed the battery and I have changed a taveror of the anti -theft and remains the same, they have also rescheduled the keys. I would appreciate if anyone knows about this ruling because according to saying in the official service it is not normal and does not leave a trace when connecting the machine to look at it since it is a "fugitive" failure

The easiest thing to do is take it where an electric or a chapero and eliminate the Atirrov
